Surge Control Devices

Surge control devices are designed to be used in the wastewater industry to remove water-borne waste from trade, manufacturing and domestic sewage. At Halgan Pty Ltd, we believe that these devices should be a part of any trade waste management strategy. Our team offers solutions that can deal with pollutants in the influent flow, including oil, grease and suspended matter. Whether you need devices retrofitted to an existing pre-treatment vessel or installed with new pre-treatment vessels to enhance their efficiency and performance by up to 95%, we’ve got you covered.

How Does a SCD Work?

Most modern wastewater flows are characterised by the typical surge nature of influent flow. A Halgan surge control device helps accommodate this. These units connect to the outlet pipe and smooth out surges in the chamber, partially balancing pollutant concentrates in the process and increasing the overall efficiency of wastewater treatment systems.

The unit is comprised of multiple packed plates, the number of which can be increased for higher flow rates. It also boasts flow-restricting components to balance the pressure between the unit and the external environment. The effluent is then discharged into the disposal or reticulated sewer system, encouraging laminar flow in the process for optimal particle separation.

What is the Best Model?

There are several things to consider and take into account when selecting the correct surge control device. This includes the maximum flow rate of your wastewater, density of greases and oils to be separated, grease storage capacity, maximum temperature of the wastewater, influence of cleansing and rinsing agents, and solids storage capacity. Talk to our experts for further advice and recommendations.

Easy to Clean & Maintain

Our surge control devices are easy to clean and maintain. Normal water pressure can remove most soft particles, while the polyethylene stops materials from sticking to surfaces. If you want to clean the device more comprehensively, simply insert a hose down the inspection opening or the internal service pipe. In addition, the unit is fixed below the water level and cannot be tampered with.

The Halgan Difference

Halgan provides custom grease traps to help any business find the perfect solution, whether you’re undergoing expansion, undertaking a renovation or starting from scratch. There is a wide range of grease trap sizes on the market, and Halgan is prepared to find the right one for you. Consider what size will suit your needs best, as a trap that is too large will waste space and may be an unnecessary cost to your business.

We offer small grease traps that can be installed simply and without too much cost to you, as no advanced lifting equipment is required. Alternatively, we can supply large grease traps that are perfect for large restaurants or butchers with a huge output of grease and oil.

Halgan grease traps meet all relevant certification requirements, including Green Star, Standards Australia WaterMark Certification, and Water Services Association of Australia (WSAA). On top of this, we have become the first pre treatment manufacturer in Australia to achieve AS-NZS 1546.1 Certification for some of our modular grease traps.
